unless the coolant is EC-1 rated it will need SCA to my understanding. I did this a few weeks back, snagged 5 gallons (youll need 4) of CAT ELC concentrate for $20 a gallon. youll need four gallons of distilled water for the final fill. 8 gallons capacity total.
for the flush, opinions vary. if you have really clean pure tap you can flush with tap water. we do, but i still flushed with distilled. it was 88 cents a gallon at wally world so i figured why not?
you could use the 50/50 mix, but ive found its more expenive. and with concentrate you have a good idea of how much was left in the sytem and can guage your mix when you fill. NOTE: there are two pipe plugs in the block, one by the oil cooler and one by the starter. mine were corroded and stripped with little force. had to use an easy out to pull them. since your in CO and have a winter, id get those plugs out (1/4" wrench head) and replace them with new allen plugs. for me 93 cents a plug at the hardware store.
also, its a good tiem to check your oil cooler for leaks, if you have oil in your coolant its a good time to rebuild the cooler since you have to drain the coolant to do it anyway. mine leaks oil outside and was going to rebuild it, but the hardest bolt to get to stripped. ill let my mechanic take care of it next oil change...
